  The final luminosity target of the Compact LInear Collider (CLIC) imposes a micron-level stability of the two-meter repetitive two-beam modules constituting the main linacs. Two-beam prototype modules have been assembled to extensively study their thermo-mechanical behaviour under different operation modes. The power dissipation occurring in the modules will be reproduced and the efficiency of the corresponding cooling systems validated. At the same time, the real environmental conditions present in the CLIC tunnel will be studied. Air conditioning and ventilation systems will be installed in the dedicated laboratory. Air temperature will be varied from 20 to 40 °C, while air flow rate will be regulated up to 0.8 m/s. During all experimental tests, the alignment of the RF structures will be monitored to investigate the influence of power dissipation and air temperature on the overall thermo-mechanical behaviour. This test program will allow for better understanding the behaviour of CLIC modules and the results will be propagated back to both numerical modelling and engineering design.
